The **W2AC-A1DY-R/N** is a specific model of an **AC Axial Fan**, typically manufactured by companies like **Fulltech** or similar industrial cooling solution providers. These fans are designed for high-performance thermal management in industrial equipment, server racks, and power supplies. --- ### 1. Technical Specifications The following table outlines the primary electronic and mechanical characteristics of the W2AC-A1DY-R/N: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Standard) | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | Approx. 20W - 30W (Depending on load) | | **Speed** | 2,700 - 3,100 RPM | | **Airflow** | ~90 - 110 CFM (Cubic Feet per Minute) | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic PBT (UL 94V-0) | | **Termination** | Lead Wires (R/N suffix often indicates wire type) | --- ### 2. Key Electronic Components & Features #### A. Shaded Pole Motor The fan utilizes an **AC Shaded Pole Motor**. This is a type of single-phase induction motor characterized by: * **Self-Starting:** No starting capacitor is required for basic operation. * **Reliability:** Few moving parts and no brushes, leading to a long operational lifespan (MTBF). * **Impedance Protection:** The windings are designed to resist burning out even if the rotor is locked (stalled) for a period of time. #### B. Dual Ball Bearing System The "A1DY" configuration usually specifies a **Ball Bearing** system. * **Longevity:** Rated for continuous 24/7 operation. * **Temperature Resistance:** Better performance in high-heat environments compared to sleeve bearings. * **Mounting:** Allows the fan to be mounted in any orientation (horizontal, vertical, or angled). #### C. Safety and Protection * **Insulation Class:** Usually rated as Class B or F, meaning the internal wiring can withstand temperatures up to 130°C–155°C. * **Dielectric Strength:** Tested to withstand high voltage (typically 1500V AC for 1 minute) between the frame and the terminals to ensure user safety. --- ### 3. Part Number Decoder (Typical) While naming conventions vary slightly by brand, the code generally breaks down as follows: 1. **W2**: Series designation (e.g., 120mm x 120mm x 38mm size). 2. **AC**: Input current type (Alternating Current). 3. **A1**: Voltage code (e.g., A1 = 100-120V, A2 = 220-240V). 4. **D**: Speed/Performance grade (High speed). 5. **Y**: Bearing type (Ball Bearing). 6. **R/N**: Specific termination or revision (e.g., Round frame or specific Lead wire length). --- ### 4. Application Areas Due to its robust aluminum construction and AC power input, this part is commonly found in: * **Industrial Control Cabinets:** Cooling PLCs and motor drives. * **Welding Equipment:** Dissipating heat from high-current transformers. * **Medical Devices:** Used in large-scale laboratory equipment. * **HVAC Systems:** Small-scale ventilation and heat exchange.
